COMBINED VENTILATOR AND DUST-ARRESTER.

Specification of Letters Patent.

Application filed October 31, 1910.

Patented Mar. '7, 1911. Serial No. 590,083.

To all whom it may concern:

Be 1t known that I, ALONZA C. CRENSILUY,

a citizen of the United States, residing at Augusta, 1n the county of Richmond and State of Georgia, have invented a new and useful Combined Ventilator and Dust-Arrcster, of which the following is a specification.

This invention relates to an attachment for railway cars, oifice buildings, etc, and has for its object the provision of means for preventing the admission of smoke, dust and cinders to the interior of the car or building without, however, preventing the passage of air intosaid car or building for cooling and ventilating purposes.

Another object is to provide a shield for intercepting smoke or dust and cinders and which is adjustable so as to be equally effec tive when the car is moving in one direction, as when moving in the opposite direction.

A further object is to provide means whereby moisture may be automatically sup plied to the shields so that the dust and other impurities in the air moving against the shields will adhere to said shields.

With these and other. objects in view the invention consists in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of .what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure 1 is a perspective view of a portion of a car having the present improvements embodied. therein. Fig. 2 is a central vertical longitudinal section through a portion of a car structure and showing the shield its pipe connections in elevation. Fig. 3 is a section on line AB of Fig. 2. Fig. 1- is an enlarged vertical transverse section through one of the deflectors and its head. Fig. 5 is a perspective view of portions of the two deflectors and showing the handle connected thereto.

Referring to the figures by characters of reference 1 designates a portion of a wall of a car and 2 designates a normally closed window arranged between jambs 3. Ventilating openings are formed within the structure 1 close to the sides of the window 2, the jambs 3 being interposed between the window and the said openings. Each open ing may be closed, preferably at its inner end, by means of a window 5. within each opening and outside of the window 5 are parallel deflectors 6 each consisting of slab 7 of wood or other material adapted to be expanded by moisture, and which is surrounded by a jacket 8 of absorbent material. The slab 7 constitutes the core of the deflector and its upper portion is grooved longitudinally as shown at 9.

The upper end of each deflector 6 projects into a slot 10 formed in the bottom of a hollow head 11, said head being attached to the deflector by means of a pin 12 or the like extending through them. The walls of the slot 10 are designed to engage the jacket 8 and, when moisture is admitted to the head 11, it will be absorbed by the slab 7 and jacket 8 so that the deflector will expand within the slot 10 and only a very small por tion of the moisture can then escape through the grooves 9. A distributing pipe 13 is arranged within the structure 1 and above the windows and is connected, by branch pipes 1 to the heads 11. These branch pipes are adapted to rotate within the joints 15 connecting them to the distributing pipe 13.

As shown in the drawings, preferably two deflectors are arranged in each opening 4-. These deflectors lie in parallel planes and the inner edge portions thereof have a handle 16 pivotally connected to them as shown at 17 in Fig. 5. By means of this handle, the deflectors 6 can be simultaneously swung to any desired angle relative to the side walls of the opening 4:, so as to deflect air currents in any direction, as desired. A drip pan 18 is located below the deflectors G and has an outlet tube 19 extending therefrom for the purpose of discharging moisture beyond the side of the car.

A reservoir 20 may be located at any suit- Arranged able point above the pipe 13 and is connected thereto by a valved pipe 21. It is to be understood that all of the deflectors 6 are connected by branch pipes 15 to the pipe 13 extending continuously within the wall of the car structure. At points adjacent the openings 4-, the pipes 13 may be provided with branch pipes 22 extending through the outer surface of the car wall and connected by a distributing pipe 23 arranged parallel with the wall of the car and located above the windows 2 and 5. Branch pipes 24 extend downwardly from this distributing pipe 23 at points adjacent the openings & and serve to connect hollow heads with said pipes 23. These heads are similar to the heads 11 and have deflectors '26 projecting into them and which are similar in construction to the deflectors 6. Each of these deflectors 26 extends longitudinally of the adjacent opening 4 and close to the center thereof, the said deflectors being perpendicular to the side of the car.

From the foregoing description, it will be observed that when the valved pipe 21 is opened, water will flow downwardly from reservoir 20 and through the various pipes to the deflectors 6 and 26. The cores of these deflectors will absorb moisture from the heads 11 and 25 and the jackets upon the cores will thus be maintained moist at all times. It is designed to keep the window 2 closed at all times, except, possibly, when the car is not in motion. The windows 5, can be left open whenever it is desired to ventilate the car. The deflectors 26 do not move relative to the wall of the car struc ture but are always perpendicular thereto. The handles 16, however, should always be shifted in the direction in which the car is moving and this will cause all of the deflectors 6 to swing so as to bring their inner edges in advance of their outer edges. As the car moves forward, the deflectors 26 will intercept portions of the air and deflect it inwardly to the openings a and, when the deflectors 6 are set in the positions shown in Fig. 8, the air will be brought directly into contact with the deflectors 6 and further diverted before passing into the car. During this tortuous movement of the air currents, the impurities contained within the air will adhere to the moist ackets on the deflectors so that only pure air will be admitted to the car. If preferred, shields 27 may be secured across the upper ends of the openings 4 and back of the heads 25 so as to prevent any air from escaping past the heads and into the openings without coming into contact with one or more of the deflectors.

It will be noted that by providing apparatus such as has been described, all impurities will be removed from the air prior to its admission to the car and the view through the window remains practically unobscured at all times.

What is claimed is 1. The combination with a structure having a ventilating opening, of a distributing pipe, a head movable relative to said pipe and communicating with the interior of said pipe, and a deflector projecting into and sup ported by the head, said deflector extending longitudinally within the opening and including an absorbent non-flexible core and an absorbent acket.

2. The combination with a structure having a ventilating opening, of a deflector outside of and fixed relative to the opening and movable deflectors mounted within the opening, each deflector consisting of an absorbent core of non-flexible material and an absorbent jacket, and means for supplying moisture to all of the deflectors.

3. The combination with a structure hav ing a ventilating opening, and a moisture collecting device within said opening, of parallel deflectors movably mounted within the opening and above said collector, each deflector including a hollow head, a nonflexible absorbent core having longitudinal grooves in one end portion thereof. said grooved end projecting into the head, and an absorbent jacket upon the core.

4. The combination with a structure having a window opening and a ventilator opening adjacent the sides of the window opening, of means for closing said ventilator openings, deflectors movably mounted within each ventilating opening, each deflector consisting of absorbent material, and means for supplying moisture to the deflectors.

5. The combination with a structure having a window opening and ventilating openings at the sides of said window opening, 0 means for closing the ventilating openings, movable deflectors suspended within the ventilating openings, the deflectors in each opening being parallel, means for simultaneously shifting the deflectors in each opening, and a moisture feeding device constituting the supports for the deflectors.

6. The combination with a structure having a ventilating opening, of a plurality of heads, a support for the heads, said support constituting means for supplying moisture to the interiors of the heads, non-flexible absorbent deflectors depending from and supported by the heads, said heads constituting means for supplying moisture to the deflectors, and means pivotally connected to the deflectors for simultaneously moving them about parallel axes.
